01 -  Preheat oven to 400°F. Grease a 12-cup muffin tin or line with paper liners. 
 02 -  In a large mixing bowl, whisk together flour, baking powder, baking soda, kosher salt, and 2 tablespoons granulated sugar until evenly blended. 
 03 -  Add cold, cubed butter to the dry mixture and use a pastry cutter or fork to work in the butter until the mixture resembles coarse crumbs. 
 04 -  Stir shredded sharp cheddar cheese into the flour-butter mixture until distributed. 
 05 -  In a separate bowl, beat together whole milk and egg, then gently fold into the dry mixture until just combined. Avoid overmixing. 
 06 -  Divide the dough evenly among the muffin cups. Bake for 16 to 18 minutes until golden brown and a toothpick inserted in the center comes out clean. Cool muffins in the pan for 5 minutes, then transfer to a wire rack. 
 07 -  While muffins bake, mix 1/3 cup granulated sugar and ground cinnamon together in a shallow bowl and set aside for coating. 
 08 -  Melt 1/4 cup unsalted butter in a small saucepan over low heat. Stir in pure maple syrup and bourbon; remove from heat. 
 09 -  While biscuit muffins are still warm, brush generously with maple bourbon butter, then roll or sprinkle with cinnamon sugar to coat. 
 10 -  Once muffins are cool enough to handle, slice each horizontally in half. Thread 2 to 3 muffin halves onto each wooden skewer, pressing gently to secure. 
 11 -  Drizzle with any remaining maple bourbon butter before serving, if desired.
